Letters Patent No. 103,447, dated May 24, 1870.

, W IjMPROVEMENT IN ADJU$TABLE CONNECTIONS 01" SUCKER RODS Tb I BEAMS.

The Schedule referred to in these Letters Patent and. making part of the name To'all whom it may concern Be it known that I, ADAM Goon, Jr., of Titusville, in the county of Bradford and State of Pennsylvauia, have invented certain new and useful Improvements in Devices for Adjusting the Sucker-Rods of Oil-Well Tubes; and I do hereby declare the following to be a full, clear, and exact description thcrcof, reference being bad to the accompanying drawings of the same, which make part of this specification, and in which- Figure 1 represents an elevation of an adjusting and clamping device embracing my improvements.

Figure 2 represents a vertical section.

Figure 3, a horizontal section of the same.

Figure 4 represents a view of the sectional screw- I clamping tube detached from its socket.

My invention relates to a; 'device applied to the walking-balm, which gives motion to the sucker-rods of oil-wells, and is used for securing what is known as the polished rodwhich connects the string of suckerrods with the walking-beam.

.The invention consists in constructing theadjuster with a flaring socket for the reception of a flaringshaped sectional screw-tube, through which the polished connecting-rod passes, and within which it is adjusted and clamped, so as to maintain a firm connection with the walking-beam. The connecting-rod is of polished wrought iron, about twelve feet long, and connected at its lower end to the string of sucker-rods, and in attaching this rod to the walking-beam, it is .i'ound ditficult to make the connection, by reason of the rod being either too long or too short, and in the former case requires to be cut ofi to the proper length, which is not only expensive, but inconvenient and troublesome.

My invention obviates thcse'difiiculties, and enables -me to connect the clasp and adjust the polished rod directly with the walking beam,-without. regard t6 the length of said polished rods In the accompanying drawings- A represl llits a metallic socketed encircling support, provided witi journal bearings, B, on opposite sides thereof, fitted into suitable boxes, secured to the end of the walking-beam. V

,The socket a of tbis'bearing support A is'made flaring vertically, with its smallest end below, into which is fitted a clamping tube, 0, the upper portion of which is enlarged, and llas inclined sides, which fit upon the inclined sides of the flaring socket a, so as to form a vertical seat for the screw-clamping tube.

This enlarged and is split, or made in sections, 1), so as to be expanded and contracted in adjusting and clamping the polished rod D, which passes through it." ,The diameter of the enlarged end is, therefore, greater piece A, draws tlie'sectional tube 0 down upon its flaring seat, and, as thcpressure is equal on all sides of the'fiaring end of the tube, the sections b thereof must be pressed toward the center, and firmly clamp the polished rod within its socketed bearing-so that it can neither move up nor down, but must communicate the motion of the walking-beam to the suekerrod without slipping, while admitting of its adjust ment, by simply unclampiug and clamping the screwnut E against the socketed bearing.

I have shown and described an adjusting device with its clamping tube split only through a portion of its length, butit is obvious that the tube maybe split on one side throughout its length, and that the clamping tube may be made to screw 'di-rectly into its screwsocket, and thus clamp the rod within it without the use of a separate clamping-nut,-and the invention may be adapted to any purpose for which it may be found applicable.

Having described my invention,

I claim, in combination with a walking-beam and polishedconnecting-rod D, of oil-pumps, the socket support A, having journal-bearings B, the split clamping tube 0, and the clamp-nut E, for the purpose of allowing the adjustment of the polished connectingrod, without the necessity of cutting it oil, as heretofore, the whole constructed and arranged as herein shown and described.
